باب مِيرَاثِ الأَخَوَاتِ مَعَ الْبَنَاتِ عَصَبَةً
Sahih al-Bukhari, Book of Laws of Inheritance (Al-Faraa'id)(view book)
Narrated Al-Aswad:
Mu'adh bin Jabal gave this verdict for us in the lifetime of Allah's Apostle. One-half of the inheritance is to be given to the daughter and the other half to the sister. Sulaiman said: Mu'adh gave a verdict for us, but he did not mention that it was so in the lifetime of Allah's Apostle.
حَدَّثَنَا بِشْرُ بْنُ خَالِدٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، عَنْ شُعْبَةَ، عَنْ سُلَيْمَانَ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، قَالَ قَضَى فِينَا مُعَاذُ بْنُ جَبَلٍ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ النِّصْفُ لِلاِبْنَةِ وَالنِّصْفُ لِلأُخْتِ. ثُمَّ قَالَ سُلَيْمَانُ قَضَى فِينَا. وَلَمْ يَذْكُرْ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ.

Narrated Huzail:
'Abdullah said, "The judgment I will give in this matter will be like the judgment of the Prophet, i.e. one-half is for the daughter and one-sixth for the son's daughter and the rest of the inheritance for the sister."
حَدَّثَنِي عَمْرُو بْنُ عَبَّاسٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ، حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي قَيْسٍ، عَنْ هُزَيْلٍ، قَالَ قَالَ عَبْدُ اللَّهِ لأَقْضِيَنَّ فِيهَا بِقَضَاءِ النَّبِيِّ ﷺ لِلاِبْنَةِ النِّصْفُ، وَلاِبْنَةِ الاِبْنِ السُّدُسُ، وَمَا بَقِيَ فَلِلأُخْتِ.
